Backend Engineer (USA)

About the role

As a Backend Engineer at Freehand, you will build the distributed systems, APIs, and AI agent infrastructure that power AI-driven enterprise execution. You will design and scale backend services that orchestrate agents, enforce business rules, integrate deeply with ERPs and financial systems, and ensure that every action taken by AI is secure, traceable, and reliable. This is not CRUD SaaS work. You will be building the backend for autonomous systems handling real money and real risk—and the observability and testing infrastructure to keep those systems trustworthy at scale.

Responsibilities

• High-throughput, low-latency backend services that power AI agent execution
• Workflow orchestration systems for complex, multi-step enterprise processes
• Rule engines and policy enforcement layers for enterprise compliance
• APIs and integrations with ERPs, procurement tools, payment rails, and data providers
• Observability, audit, and traceability systems for AI-driven decisions
• Secure data pipelines handling sensitive financial and operational data
• Agent execution runtimes, multi-agent coordination, and observability pipelines for AI-driven workflows
• Evaluation and testing harnesses to validate agent behaviour, reliability, and output quality
• Design and build scalable backend services using modern system design principles
